Abstract
A safety switch mechanism for use on a conveyor system includes a lever adapted for pivotal attachment to a non-moving part of the conveyor system. A non-contact safety switch has a first switch part attached the lever and a second switch part fixed relative to the lever. The safety switch has an open position where the first switch part is angularly offset from the second switch part relative to a lever pivot axis and a closed position where the first switch part is aligned with the second switch part. A trigger block is adapted for attachment to a moving part of the conveyor system. The lever is configured as a pendulum and in an equilibrium position of the lever the safety switch is in the open position. The trigger block is configured to contact and pivot the lever moving the safety switch from the open position to the closed position.
